Serlvlet accessibility

[ramu_indian]

Is it possible that we restrict our servlet's accessibility to limited number of users?
If so how?

Please help.

what you can do is test of the accessing user is a specific user if so then allow them further down in the servlet else just don't allow them full access...there are ways to achieve it
1. Write a routine in the servlet itself that checks who is the user
2.Write a filter class and filter accessing users, if a valid user then allow access to servlet else redirect to where ever

Thank you. But what i mean to ask is not validating the user. How to limit the total no. of actual clients accessing a particular servlet. Assume that I am developing a banking application. And there is a servlet that tests whether the username and password is correct or not. Now if one million users are trying to log-in. And the servlet is in action. In what way the servlet will serve all the one million users in order to give results to all the users. I want my servlet to WORK FOR ONLY first 100 PEOPLE who log in.

well (if I understadn correctly) you may want to look into the option #2 in my earlier post.
Using a filter you can maintain that how many users have been logged in for every request and as soon as a user is logged of you can allow the next requestee to login. Essentially you will have to come up with a logic that will calculate what you want to set a business rule for login or logged in users.
